-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:003 http://www.mandriva.com/security/ _______________________________________________________________________ Package : poppler Date : January 5, 2006 Affected: 2006.0 _______________________________________________________________________ Problem Description: Multiple heap-based buffer overflows in the DCTStream::readProgressiveSOF and DCTStream::readBaselineSOF functions in the DCT stream parsing code (Stream.cc) in xpdf 3.01 and earlier, allow user-complicit attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with an out-of-range number of components (numComps), which is used as an array index. (CVE-2005-3191) Heap-based buffer overflow in the StreamPredictor function in Xpdf 3.01 allows remote attackers to execute arbitrary code via a PDF file with an out-of-range numComps (number of components) field. (CVE-2005-3192) Heap-based buffer overflow in the JPXStream::readCodestream function in the JPX stream parsing code (JPXStream.c) for xpdf 3.01 and earlier allows user-complicit attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with large size values that cause insufficient memory to be allocated. (CVE-2005-3193) An additional patch re-addresses memory allocation routines in goo/gmem.c (Martin Pitt/Canonical, Dirk Mueller/KDE). In addition, Chris Evans discovered several other vulnerbilities in the xpdf code base: Out-of-bounds heap accesses with large or negative parameters to "FlateDecode" stream. (CVE-2005-3192) Out-of-bounds heap accesses with large or negative parameters to "CCITTFaxDecode" stream. (CVE-2005-3624) Infinite CPU spins in various places when stream ends unexpectedly. (CVE-2005-3625) NULL pointer crash in the "FlateDecode" stream. (CVE-2005-3626) Overflows of compInfo array in "DCTDecode" stream. (CVE-2005-3627) Possible to use index past end of array in "DCTDecode" stream. (CVE-2005-3627) Possible out-of-bounds indexing trouble in "DCTDecode" stream. (CVE-2005-3627) Poppler uses an embedded copy of the xpdf code, with the same vulnerabilities. The updated packages have been patched to correct these problems. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3191 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3192 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3193 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3624 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3625 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3626 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3627 _______________________________________________________________________ Updated Packages: Mandriva Linux 2006.0: eed45eed8ae99ca240c873c03a5cbf40 2006.0/RPMS/libpoppler0-0.4.1-3.1.20060mdk.i586.rpm 8af1cf9763672dd33d2211958a8171ba 2006.0/RPMS/libpoppler0-devel-0.4.1-3.1.20060mdk.i586.rpm 867596ef4e09751ed3d4e1e7a4e640da 2006.0/RPMS/libpoppler-qt0-0.4.1-3.1.20060mdk.i586.rpm fd4736b863ce01d20bd6d2ae1228417a 2006.0/RPMS/libpoppler-qt0-devel-0.4.1-3.1.20060mdk.i586.rpm c40f77c8b63d7af311801ab97ef8f72e 2006.0/SRPMS/poppler-0.4.1-3.1.20060mdk.src.rpm Mandriva Linux 2006.0/X86_64: d4dc20ee3d3cc10d39c3b9a05214ca7c x86_64/2006.0/RPMS/lib64poppler0-0.4.1-3.1.20060mdk.x86_64.rpm 0e577cbd784f733c54369cc153777978 x86_64/2006.0/RPMS/lib64poppler0-devel-0.4.1-3.1.20060mdk.x86_64.rpm 7145106c6988a8b99a0622265cc5b24a x86_64/2006.0/RPMS/lib64poppler-qt0-0.4.1-3.1.20060mdk.x86_64.rpm 913bb80df9cc19fe5948b23633915529 x86_64/2006.0/RPMS/lib64poppler-qt0-devel-0.4.1-3.1.20060mdk.x86_64.rpm c40f77c8b63d7af311801ab97ef8f72e x86_64/2006.0/SRPMS/poppler-0.4.1-3.1.20060mdk.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
